SHUTTER-BOWER.

SEEGIFKGATION forming part of Letters Patent No. 670,780, dated March 26, 1901.

Application iiled July Z5, 1900. Serial No. 24,848. (No model.) A

T0 (0M zii/1,011?, it may concern:

Be it known that l, JEFFERSON HOOPES, a citizen of the United States, residing at Marshallton, in the county of Newcastle and State of Delaware, haveinvented certain new and useful Improvements in Shutteisowers; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to attachments for shutters, and has for one object to provide a device which shall serve to hold a shutter at varying degrees of adjustment between a wholly closed and an entirely open position.

A further objectmf the invention is to provide novel means whereby the arm employed for retaining the shutter in its adjusted position may he utilized Ialso for the purpose of retaining said shutter closed in a locked condition, that it may not be opened from the outside.

Furthermore, the object of the invention is to provide means whereby the joint of the arm and its bracket will permit of certain ad justmenis in order that the secu ring-arm may assume an incline position, which is neces sary to accomplish certain results, as will be more fully explained.

With the above and other objects in view the invention consists in the details of construction and in the arrangements and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote correspondingparts in the several views, and in which-- Figure l is a perspective view of aportion of a window-sill and the shutter with the attachment adj usted to hold the shutter open, and in dotted lines an intermediate adjustment of the parts is illustrated. Fig. 2 is a horizontal sectional view of a shutter, showing the attachment in plan. Fig. 3 is a detail view of the ball-and-socket joint.

In the drawings, l indicates a windowframe, a the sill, and 2 a plate on the frame, having an upturned stud 3, the inner face of which stands at right angles to the upper l surface of the plate. An elongated plate 4 is also secured to the sill and is provided with a series of apertures 5, suitably spaced. The plate 4 has formed therewith a stud 6, having its side recessed, as shown at 7, the purpose of which will be presently described.

The means for holding the shutter at varying degrees of adjustment comprises an arm 8, having an angular end 9, adapted to enter the apertures G of the plate, and it will be observed that the position of the shutter may be regulated as shown by dotted lines, according to the requirements and desires of the user. The arm is attached to the shutter through the agency of a bracket lO, having ears l1, with their facing surfaces recessed to form sockets, in which the ball l2 on the end of the arm 8 is seated, thus producing a ballandsocket joint between the arm an d bracket. This feature of the invention is a very important one, for while the pivotal point would be in a vertical plane when the end of the arm is in engagement with the plate 4, the plane of the pivot would change when the arm is in an inclined position, as shown in to lock the shutter in a closed position.

A bracket 13 is fastened to the outer edge of the sill, near the end, for engagement of the arm when the shutter is thrown entirely open.

As shown in Fig. l, the arm is wedgedbetween the studs 3 and 6, and it is my purpose to shape the arm elliptical in cross-section, so that it will cam over the edge of the upper end of the stud and spring into engagement with said stud and in the recess 7. When in this position, the arm is not lying in a Thus the function and the advantage of the ball-and-socket joint of the arm is evidenced, as it permits the arm to be swung over the stud and depressed on an incline until said arm springs into the recess of the stud.

The construction, operation, and advantages will, it is thought, loe understood from the foregoing description, it being noted that various changes in the proportions and other details of construction may be resorted to for successfully carrying the invention into practice without departing from the scope of the claims.

l. In a shutter-bowing attachment, a flexible arm connected to a shutter by a balland-socket joint, a plate on the Windowframe having` a stud, and second plate having apertu res and a stud, and a right-angular extension on the arm adapted to enter the apertures of the plate and means whereby the arm is sprung between the studs for holding the shutter closed.
